Ming Reynolds is one of the Missing Children. Her true identity is a minor Chinese princess from the 4th Century. After the scuffle in the cave, JB grabs her and uses her as a shield, saying that Mr. Hodge and Gary wouldn't hurt one of the missing. Mr. Hodge reveals her identity and says she's such an obscure princess, he would be willing to sacrifice her to keep the other missing children.
Ming orginially thought the fight that broke out in the cave/time hollow was a role play. When JB grabs her, she says it's too realistic and wants them to stop.
